SPECIFICATION forming part of Letters Patent No. 580,617, dated April13, 1897.

Application filed MaTOll 6, 1896.

Serial No. 582,024:- (No model.)

To all whom it may concern.-

Be it known that I, HERMAN KREUSLER, a resident of Kreischerville,Richmond county, State of New York, have invented a certain new andImproved Printing-Telegraph, of which the following is a specification.

My invention relates to printing-telegraphs, and more especially to thatclass of telegraphs wherein the marking or printing is done by means ofan instrument actuated or moving synchronously with a transmittinginstrument.

My invention consists in the construction hereinafter set forth andclaimed.

My invention will be understood by referring to the accompanyingdrawings, in whichi Figure l is a general diagrammatic view of apparatusembodying my invention, showing the circuit connections in detail. Fig.2 is a detail diagrammatic plan View of a transmitting apparatusembodying my invention. Fig. 3 is a detail diagrammatic plan view of areceiving apparatus embodying my invention and corresponding to andcapable of operation in conjunction with the transmitter shown in Fig.2. Fig. 4 is a detail side elevation of the transmitter, showing alsothe circuit connections. Fig. 5 is an enlarged detail view of the rearend of one of the keys of the transmitter-keyboard. Fig. 6 is anenlarged detail View showing a pair of the cooperating contacts of thereceiver, the same forming the circuit-closer of the top levermagnets.

Stated generally, the apparatus illustrated consists of a transmittercomprising a keyboard and a transmitting-arm, which transmitting-armcontrols the line-circuit, in which is placed a receiver havinga similartraveling arm which controls the local circuit of a suitable type-writeror mechanical-writing machine. These transmitters and receivers may beplaced upon the line in various numbers and variously arranged, but thepreferable mode of connecting and arranging them is shown in Fig. 1.

Before proceeding to describe the general system I will now describe thetransmitter and the receiver separately and will then describe theirconnections and conjoint action."

Referring particularly to Figs. 2, 4, and 5,.

a contact-arc G, also mounted upon the baseboard. Series of keys H arepivotally mounted in proximity to the contact-arc G, the said keys beingshown as pivoted to a curved rod I, mounted in brackets d, rising fromthe baseboard and cooperating with a contact-plate J, above which theyare suspended. The keys converge and their inner ends are adapted toarrest the arm F as it moves. Referring now to Fig. 5, which shows therear end of one of these key-levers H, we note that the rear end isprovided with an upturned tang e, which tang is shown as inclined at itstop and provided with a notch f. These, keys,which are shown asconverging toward the contact-arc G, have their rear ends in such closeproximity thereto and to the path of travel of the end of the arm F asto cooperate with the end of the swinging arm F, as will more fullyhereinafter appear. Magnets K are mounted upon the base-board beneaththe pivoted armature E and serve to swing the said armature and itshorizontally-swinging contact-arm up and down, the said armature beingconnected with the said arm by a pivotal connection and also by means ofa restoring-spring g. The driving means for the worm-shaft O isconstituted by a spring-motor L, which is provided with a control-wheelM, governed by a pivoted detent N, to which an armature O is fastened,magnets P upon the base-board serving to control the said armature. Inlieu of the spring-motor and detent apparatus other driving means may beused. The magnet P, as

well as the magnet K, is in the present instance controlled by a localcircuit manipulated through the keyboard. This local circuit is shown asconsisting of a wire 1, which connects with the said magnet and with therod I, which is in common electrical connection with the keys H, each ofwhich forms during the normal state of a transmitter one pole of thelocal circuit, the other pole being constituted by the contact-plate J,from which the 'wire 2 leads to the magnet K, the said magnet K beingconnected to the battery 4 by a wire 3, the opposite pole of the batterybeing connected by a wire 5 with the magnet P, so that when a key isdepressed we have a circuit from the battery by wire 5, magnet P, wire1, rod I, key I-I, plate J, wire 2, magnet K, and wire 3 back to thebattery. The effect of the passage of the current will be to release thedetent N from the control-wheel M and swinging the armature Edownwardly. The effect of releasing the control-wheel will be to startup the motor K, which, driving theworm-shaft C, will swin the rod F(whose bowl has been entered into the groove of the shaft by the swingof the armature E) in the direction of the arrow.

The receiving end of the circuit is shown in Fig. 3, to which referenceis now invited. In this'figure, Q is a motorhaving a control-wheel R,which is controlled by a detent carried upon a pivoted armature h-underthe influence of a magnet S. This motorserves-to drive a worm-shaft T,which is locatedin proximity to a receiving-table of contacts shown asaseries of insulated contact points c' 'i i 2' t, &c. Pivotedv upon averticallyswinging armature U, which is controlled by a magnet V, is anarm W. This arm is pivoted to swing in a horizontal plane and isconnected with a restorin g-sprin g j,-Whi 3h serves to restore it toits initial position, and is also provided with a bowl- 7c,which entersthe groove tin the worm-shaft. This arm is adapted for cooperation withthe contact-points 1 2 1 ;-&c., before referred-to. and is swung alongthe path formed by the said contact points when the motor Q is operated.The

' magnets S and V are in the line-circuitand are actuated by the sameimpulse, the magnet S operating to release the detent h from thecontrol-wheel R, whereupon the motor starts up, and the magnet V-operating to swing the armature U- and arm WV downward to enter the bowl7t into the groove 25 in the worm-shaft T, so thatas soon as the-circuitof the magnets Sand V is closed the arm W will be swung upon itsvertical pivot. This arm will not, however, contact withthecontact-points 71,850., until the circuit of the-magnets S and V isbroken, for the arm travels below the contact-points, as 'will be seenin the detail side View, Fig. 6. As soon, however, as the circuit of themagnets S and V is broken the motor will ceaseto operate and thearmature U will swing upward, carrying thearm into contact with one ofthe contactpoints, thereby touching the contact-point which the arm.maybe opposite at the moment of the breaking of the circuit, the-saidarm being of such a length as to just touch the contact-point as itrises past the-same.

The arm is raised by the restoring-springl above the level of thecontact-points and is guided in its upward movement by the bowl workingagainst the edge of the groove in the worm-shaft, the said bowl being ofsuch length as to remain in contact with the groove until the arm hastouched and has been raised above thelevel of the contact-point which itmay be opposite, when the bowl passes out of the groove and the spring]is permitted to swing the arm back to its initial position.

The said swing takes place above the level of the contact-points and outof contact therewith by reason of the fact that the bowl does not-leavethe groove until the end of the arm -ula-tions of this writing-machine!may be effectedbyregulating the stoppage of thearm W, which is thereceiving-arm, in front ofany predetermined contact-point.

Referring now to Fig. 1, we have thegeneral arrangement of circuits and.apparatus. In this figure it will be noted that the linewire A isconnected to the wire 13,. which connects with the-magnet S, -which:magnet S is connected-withthe magnet V bywi-re 14,

the magnet V being connected to; the linewire A :in which the battery Ais interpolated and which is-connected to the contact strip or rail G-of the transmitter,- theilinewire A being connected to the armatureE ofthe magnetK, so that as soon as the mag- .net K- is operated to bring=the-arm=F into contactwiththe contact-rail G? thecircuit will be closedthrough the magnets-S and V. As before mentioned, the closing'of thecircuits through these magnets will have the effect of starting upthemotorand-driving the arm TV through the medium of r the wormshaft 'T.As longas the circuit is closed, which will be-as long as the arm Fcontacts with its rail, the arm W will continuetomove, and the motors Land Q being synchronous motors the arms will be driven atthesame rate ofspeed-and-will= consequently, in the apparatus shown, traverseequal'spaces.

- It-will' be observed, therefore, that 'by controlling the extent ofthe horizontal. swing-of the arm F- the-extent of swing-ofthearnrW maybe very exactly controlled, so as to 'produce the desiredeffects uponthewriting-machine Y, which effects may,'as beforestated, be ofvarious-kinds, the magnets being connected, as before pointed out,tothe-separate insulated contact-points z','i,'t' &c.,-and being.provided-with a common return 15, which is electrically connected withthe armW, so that thearmNV will close the circuitof-any magnet bytouching the contact to which the said magnet is connected. The keys ofthe keyboard regulate the distance of travel of the arm F-that is tosay, by depressing a key a local circuit is closed, by which the arm isengaged with its propelling worm-shaft and carried along thereby, thearm W following the movements ofthe arm F until the end of the arm Fcomes in contact with the tang e of the key H, when it will ride up theincline thereof and be thereby elevated from contact with the arc G,breaking the controlled circuit of the arm W and bringing the said armto rest, the notch f engaging the arm to prevent a retrogression thereofuntil the key H is released, whereupon the restoring-springs g and awill restore the arm F to its initial position, the arm WV beingrestored by its restoring-springsj and Z. These manipulations may berepeated as'often as desired.
